RAIL-ELEVATI'NG APPARATUS.

Specification of Letters Patent. Patented J 11118 22, 1911.5.

Application filed March 23, 1915. Serial No. 16,385.

- To all whom it may concern:

' ratus. Fig. 2 is an end view.

Be it known that I, GEORGE W. ROBERTS, a citizen of the United States, residing at Columbus, in. the county of Muscogee and State of Georgia, have invented certain new and useful Improvements in Rail-Elevating Apparatus; .and I do hereby declare the 'f0llowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

ThlS invention relates to new and useful improvements in machines for laying railway tracks and for other purposes and consists of a simple and eflicient apparatus of this nature having various details of construction, combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claim.

My invention is illustrated in the accompanying drawings, in which:

Figure 1 is a side elevation of the appa- Fig. 3 is a detail sectional view on line 3-3 of Fig. 1, and Fig. 4 is a detail view.

Reference now being had to the details of the drawings by letter, A designates a truck having wheels B and C mounted respectively upon the axles B and 0. ,Tracks D are mounted upon the truck and each has an upturned end E serving as a stop to limit the movement of the carriage F, which latter has sides F, the lower ends F of which are bent inwardly and are adapted to extend underneath the flanged tread surface of the tracks D, as shown clearly in the sectional view of the drawings. Said carriage has mounted therein the shafts H uponwhich the flanged wheels I are mounted and which ride upon the tracks D. Rising from the carriage is a jack screw J having a vertically movable post L and upon which the forked socket member M is swiveled, which latter is recessed at its lower end and rests frictionally upon the upper pointed end of the post L. The arms of said socket member are apertured for the reception of a pin 0 which passes through the elongated slot R of I thelever R, which latter is notched at S .near one end to receive the link of a chain T which is connected to the grapple hooks W.

In operation, it will be noted that the truck is so constructed as to ride upon the rails temporarily or otherwise laid for the purpose and, through the medium of the carriage mounted as described, the latter may be moved back and forth in order to bring the grapple hooks in proper position to grip the rail and, owing to the swivel connections shown and described, the lever may be held in different positions and the rail raised and swung to proper position, the jack screws being utilized to regulate the elevation of the post which carries the swiveled forked member.

What I claim to be new is:

A rail elevating apparatus comprising a truck with rails thereon, a carriage with a bottom having downwardly extending parallel sides with their lower edgesinwardly bent, adapted to engage the under edge of the tread surface of the rails, axles journaled in said sides, wheels upon the axles, and a lifting 'ack having a base which is secured to sai bottom of the carriage.

In testimony whereof I hereunto afiix my Signature in presence of two witnesses.
